CLOSURE FOR GAS-RETORTS.

SPECIFICATION forming part of Letters Patent No. 758,935, dated May 3, 1904.

I Application filed February 15, 1904. Serial No. 193,599. (No model.)

To all whom it may concern:

Be it known that I, SILAS BENT RUssELL, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Closure for Mouthpieces for Gas-Retorts, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the 1 same, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in part in the combination, with a retort-mouthpiece, of a door therefor, a locking-bar, a latch carried by said mouthpiece and engaging said bar, a supporting-plate engaging said bar and supporting said door, and connections between. said supporting-plate and mouthpiece for tightening said door.

My invention also consists in certain other novel features and details of construction, all of which are described in the following specification and pointed out in the claims a-flixed 5 hereto.

In the accompanying drawings, which illustrate one form of retort-mouthpiece made in accordance with my invention, Figure 1 is a top plan view on a reduced scale, showing 3 the complete mouthpiece with the door or lid in its open position. Fig. 2 is a front elevation also on a slightly-reduced scale, showing the door closed. Fig. 3 is a horizontal central section. Fig. 4 is a vertical central section through the lid or door together with the locking-bar and supporting-plate. Fig. 5 is partly a top plan view and partly a section of the sup porting-plate. Fig. 6 is a section on the line 6 6 of Fig. 5. Fig. 7 is a section on the 4 line 7 7 of Fig. 5. Fig. 8 is a front elevation of the door or lid alone, and Fig. 9 is a section on the line 9 9 of Fig. 2.

Like marks of reference refer to similar parts in the several views of the drawings. 10 is the mouthpiece, which may be of any usual form and is preferably provided with a flange 11, by means of which it is secured in position against the retort.

12, Fig. 1, illustrates a pair of stand-pipes arranged adjacent to the mouthpiece. 5

13 is the door or lid, which is adapted to fit against the front face of the mouthpiece 10 so as to make a gas-tight joint therewith.

1 1 is a lug carried by the mouthpiece'10. Passing through the lug 1 1 is a rod or shaft 15. At the upper and lower ends of the rod or shaft 15 are eccentrics 16, Figs. 3 and 9, which engage with bearings 17 on the supportingplate 18. The rod or shaft 15 is provided with an L-shaped handle 19, by means of which it, together with the eccentrics 16, is operated to move the supporting-plate 18 toward or from the mouthpiece 10. The supportingplate 18 is provided with a grooved portion 20, adapted to receive one end of a locking- 5 bar 21, and the lid or door 13 is provided with a groove 22 for receiving the grooved portion 20 of the supporting-plate. The locking-bar 21 is pivoted between a pair of lugs 23,formed on the lid or door 13, by means of a bolt 24 7 passing through said lugs. The bolt 2 1 is provided with a nut 25, which is engaged by a groove or slot in the under face of the lower lug 23.

The mouthpiece 10 is provided at the opposite side from the lug 1A with a projection 27, which cooperates with a latch 28 to retain the end of the locking-bar 21. This projection 27 and latch 28 are of the usual form and will not be particularly described. The supporting-plate 18 is provided with a bearing 29, which forms a fulcrum for the locking-bar 21. The locking-bar 21 is secured to the supporting-plate 18 by means of a bolt 30, passing through an opening 31 in the said supporting- 5 plate and through an eye 32 on the end of the locking-bar 21. The locking-bar 21 may be adjusted with relation to the supporting-plate by means of a nut 33 on the end of the bolt 30. The bolt 30 is provided with a T-shaped 9 head 34, which is adapted to pass between the inturned ends of a pair of lugs 35, formed on the back of the supporting-plate. 30 is placed in position before the door is secured to the mouthpiece, and after the said door has been secured in position the lug 14. will prevent the rotation of the bolt, so that the bolt will be firmly held in position by means of the inturned ends of the lugs 35. The supporting-plate 18 is also provided with a bearing 36, (best shown in Fig. 5,) which bearing is adapted to rest against the edge of the upper lug 23 on the door, so as to prevent lateral movement between the supportingplate and door. ()n the rear of the supporting-plate 18 is asupporting-lug 37, upon which rests a lug 38, formed on the door or lid 18. This lug 38 has a concave face, which is adapted to rest against a convex bearing 39 on the upper face of the lug 37.

In the operation of my device when the door is closed the end of the locking-bar 21 is engaged by the latch 28, thus securing it in position. The handle 19 is then turned to cause the eccentrics 16 .to draw the rear end of the supporting-plate toward the retort-mouthpiece. This movement is communicated through the bolt to the rear end of the locking-bar. This locking-bar through this action on the bolt 2 and on the fulcrum 29 of the supporting plate draws the door or lid 13 firmly against the end of the mouthpiece 10, and at the same time aslight lateral movement between the door and mouthpiece is caused by the action of the eccentrics 16, so that the door is caused to make a gas-tight joint with the mouthpiece. In case the door or mouthpiece becomes worn the wear can readily be taken up by turning the nut 33, thus drawing the rear end of the locking-bar 21 closer-to the supporting-plate 18.

While my mouthpiece is simple of construction, it is very reliable in action and is not liable to get out of order. At the same time all the parts are easily manufactured, and if one part becomes worn out or broken itcan easily be replaced by another part.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
